1. I want to use the configuration of Postfix, Procmail Spamd /Spamc. I have the spamd daemon running. I tried to have the box start spamc to check for spam. I am not sure that I have set it up correctly.
Your call to spamc looks fine. What did you pass to spamd when you started it?
For some testing on your own, you can try this:
First start spamd with debugging on, maybe even non-daemonized in a extra console.
Then run some sample messages through spamc on the command line:
cat sample-spam.txt | spamc
That will at least let you see some of what's going on. (sample-spam.txt is included in the tarball, or you can use just about any single-message email file)
